Thank you so much George, I haven't gotten it to work yet, but I'm trying to figure it out - it's exactly what I need!

Hi Arvid,
The little macro below should do the trick.
In ImageJ, just open a text window and paste into the window.  In Fiji,
open a new Script, select ImageJ macro as the language and paste the text
into the window.
Edit the xTranslate and yTranslate as necessary.  Open your stack and Run
Macro.
FYI, if you go to Plugins>Macros>Record, you can find the commands to run
ImageJ's functions and put these into a simple macro.  For your purposes,
it just needed to be put into a loop to run through the stack and edited to
use n, 2n, 3n, etc.

//Stack needs to be open

xTranslate=1;
yTranslate=0;
/*Translate a stack of images so that the first image is moved n
pixels in the X direction, the second moved 2n pixels, the third 3n pixels
and so on..
the variable "n" is represented by xTranslate and yTranslate
*/


for(i=1;i<=nSlices;i++){
setSlice(i);
run("Translate...", "x="+i*xTranslate+" y="+i*yTranslate+"
interpolation=None slice");
}
